Air Pressure Monitor

When connected to a tyre or sports ball, the current air pressure value will display on the screen.

Checking the Tyre Pressure

Before installation, please check the user manual of the tyre/ball for the required inflation pressure to ensure safety and avoid personal injury.

TyreInflation Pressure Ranges are written on the tyre side walls of cars, bicycles and motorcycles. Inflation Pressure is directly related to the load capacity of the tyre. Please refer to the user manual of your vehicle for specific pressure recommendation.

BallInflation Pressure Ranges for sports balls are written by the valve hole.

Preset the Inflation Pressure

Mode SwitchPress the Mode button to cycle through the various Inflation Modes. Please select the correct air pressure unit before inflation. Hold down the Unit Switch Button to cycle through the various units such as: psi, bar, KPA, KG, CM2, etc.

Free Mode: the preset pressure can be set manually. Values and Units used can be saved.Adjustable Range: 3-150psi

Adjusting Preset ValueAfter selecting the preferred mode, press the+ or – button to adjust the preset value. Press and hold down the+ or- button to adjust the preset values quickly. When the Preset Values flash on the display screen this indicates that the Tyre Pump is in the Pressure Value Settings. After selecting the preferred values, the numbers will stop flashing and show the current air pressure values on the screen.


Starting Inflation

After turning the air pump on, press the Power button to start inflation. The current values will display on the screen and change accordingly. Please be aware that this device makes a noise between 90-105dB during inflation.The temperature of the Air Hose and the Tyre Pump can increase after prolonged use, so please do not touch them immediately after use.

Stopping InflationThe Tyre Pump will automatically stop inflating when the air pressure reaches the preset value. You can also manually stop inflation by pressing the Power Button during inflation.

Attention: the inflation pressure range for some items, i.e. balloons, toy balls, swimming ring, is lower than the pressure range of the pump. This means that inflation cannot be stopped automatically by setting the air pressure value. Please be cautious when inflating items of this sort.

BatteryWhen fully charged, the Tyre Pump has a battery life of approximately 35 minutes when operating at room temperature (25°C).

Removing the Valve Adaptor

The temperature of the Air Hose can increase during inflation. Please be careful when removing the Valve Adaptor to avoid personal injury. Some air will leak when removing the Valve Adaptor, so please remove it quickly to avoid further leakage.

Power Off

Hold down the Power Button to turn off.When turned on, the Tyre Pump will automatically turn off when left idle for 1 minute.

If the lithium battery overheats, is struck or exposed to water, ii may cause fire, spontaneous combustion or explosion. Please do not expose this product to high temperatures.The recommend storage temperature of this product is between -10°C and 45°C. Extreme temperatures will automatically activate battery protection mode and will ,be required to be charged.-The battery may be damaged if the product is left idle for a long period of time. It is recommended to charge this product at least once every 6 months.-This product has a built-in DC motor, so there be a spark during operation. Please do not use in a flammable or explosive environment.-If you hear any abnormal noises or the product is extremely hot during use, please turn ii off immediately.-Please ensure that you have selected the correct measurement unit before adjusting the inflation pressure value, otherwise this may result in over inflation or personal injury. Common unit conversion 1 bar= 14.Spsi, 1 bar= 1 00kPa.-Do not leave this product unattended during inflation.-Please use this product in a dry and clean environment since dust and dirt may cause damage to it. This product is not waterproof, so do not expose ii to water.


Trouble Solution
The inflation speed is slow. 1. Check if the battery level is low.
2. Check if the air hose is leaking.
3. Check if the connection parts on both ends of the air hose are tightened.
4. Check if the inflated object is leaking.
Unable to inflate after turned on. 1. Check if the current tyre pressure is higher than the preset value.
2. Check if the battery level is low.
The preset pressure value can’t be adjusted. Check if the product is under the incorrect inflation mode. Under the free mode with no icon lighting on, the preset value can be adjusted within 3-150psi.
Inflate normally but the pressure value displayed is zero. Low-pressure inflatable products such as balloon are not within the measurable range of the pump.
The pump has turned off automatically after the valve adapter is screwed. Hold down the “Power Button” to turn on again.
Air leaks when connecting the air hose. Tighten the air hose.
The indicator color under inflation status is not consistent with that under standby status. The lithium batteries have a distinct voltage drop in discharge process, resulting in the inconsistency of indicator color under inflation status and standby status, which is not a fault.
